Let the N be the atomic No. and M be the mass No.
The No. of Electrons=No. of Protons=N
The No. of Neutrons=M-N
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
For each isotope of Md the number of neutrons is different.Number of neutrons = Mass number of a Md isotope -101
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
The number of neutrons is different for each isotope. Number of neutrons = Atomic mass of an isotope - 104
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
Each isotope of beryllium has a different number of neutrons.
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope – atomic number
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an Fm isotope - 100
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
153 neutrons in the most stable isotope Number of neutrons = Atomic mass of an isotope - atomic number. Atomic mass of the most stable isotope of Cf is 251. Atomic number of Cf is 98.
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Pm isotope - 61
